I am not going to recommend buying salt stocks because I know little about this, but I think Morningstar’s article about salt is interesting.
It goes to show that if you can aquire knowledge about something specific like salt you can be ahead of the game because issues like this are rarely covered on Wall Street, financial magazines or newspapers. Investing your money in what you know is always a good idea because understanding an indusr=try, or commodity in this case, is half the battle in being successful at investing.
